2205 Duplex Stainless Steel Pipe
Manufacture:
Pipes shall be made by the seamless process and shall be either hot finished or cold finished.
Superior Surface Finish:
The traditional annealing:
Open furnace---Oxygen atmosphere---form Scale, tarnish the material, For more than 12m tubes
this method is hard to clean inner surface.
A special bright annealing:
Closed furnace---Intert atmosphere use noble gases(Nitrogen and argon) Preventing Oxygen to contact with material---Surface finish is clean, bright and precision, which is an excellent starting point for further process, like electro-polishing and mechanical polishing. For more than 12m tubes, this method is much cleaner smoother on both inner and outer surface.
Application:
high pressure pipe line, heat exchanger(chemical processing industry), oil and gas pipeline
Size Range:
OD:21.3-711mm
WT: SCH5/SCH10/SCH40/SCH80/SCH160/XXS(1.65mm-30.75mm)
Length: max 12000mm
